Title: Sampling method for infrared spectral measurement, and interface of high-speed liquid chromatograph and infrared spectrophotometer and infrared spectrophotometer for high precision liquid chromatograph detector
Inventor: WADA AKIO
IPC: G01N21/35
Filed: 1986-06-24
Abstract: PURPOSE:To permit the automatic measurement of an eluted sample obtd. by the preparatory sepn. with a high precision liquid chromatograph (HPLC) by combining an instrument for measuring the IR spectra of the sample deposited on a sample base surface with an interface. CONSTITUTION:A material which reflects IR rays is used as a sampling holding base 2 to hold the sample 1 thereon. A soln. of the sample 1 is dropped at a prescribed amt. thereto and the solvent is evaporated as it is or by heating, pressure reducing, or blowing of a dry gas, then only the sample 1 to be measured deposits and remain thereon. The holding base 2 on which the sample 1 is deposited in the above-mentioned manner is set in the sample chamber of an ordinary IR spectrophotometer and IR light 3 is projected to the sample 1. Then, the IR light 3 passes the sample layer first and reflects on the holding base 2; further, the light passes the sample layer again and emits therefrom as reflected IR light 4. The degree of the absorption by the sample 1 is, therefore, obtd. by comparing the reflected light 4 with the reflected light of the case in which the sample 1 is not placed on the sample base.

Abstract: PROBLEM TO BE SOLVED: To read only an arbitrary area without driving with a highspeed clock, obtain a high frame rate, and attain reduction in scale by selecting and scanning an arbitrary unit of pixel signals of a two-dimensional pixel array together at each time. SOLUTION: This shift register consists of a 1st shift switch 11 and a 2nd shift switch 12 which are cascaded to a shift register unit block 10 in stages, and opened and closed with the clock. The opening and closure of the shift switches 12 are controlled by unit blocks by a switch group 13 according to switch opening/closure information in a memory part 14. Here, an inputted start pulse ϕST is shifted by the 2nd shift switch 12 according to a shift clock ϕCK in a nonconduction unit block and placed in phase with the shift signal of the unit block of the last stage irrelevantly to the shift clock ϕCK in a conduction unit block. Therefore, the opening and closure of the shift switches can be controlled by the unit blocks, and the pixel signals can be scanned together by arbitrary units.

Title: Connection check system
Inventor: NAGATA HISAO
IPC: H01L21/8234
Filed: 1986-06-24
Abstract: PURPOSE:To simplify the connection check and to improve the reliability of check by inserting a Schottky barrier diode having a threshold voltage lower than that of a signal electrode of a MOS integrated circuit in the reverse polarity to the signal between a signal line from the MOS integrated circuit and a common electrode. CONSTITUTION:Since a threshold voltage of a P-N junction of a silicon substrate is nearly 0.7V, a current I2 shown in figure does not flow to signal lines 3-1, 11--1 via a MOS integrated circuit 10. A threshold voltage, however, of the Schottky barrier diode is nearly 0.2V, a current I1 of several tens muA-several hundreds muA flows to the Schottky barrier diode 12-1. Thus, a voltage within 0.5V being a rated voltage which can be applied to a general MOS integrated circuit in reverse direction is applied, and the continuity is confirmed by the current flowing when connector contacts 5, 2-1 are brought into contact with each other and improper contact is detected by the interruption of current if the connector contacts 2-1, 5 are brought into contact improperly with each other.

Title: Driving method of planar screen indicator
Inventor: NONOMURA KINZOU
IPC: H01J31/12
Filed: 1981-09-18
Abstract: PURPOSE:To obtain a clear picture image having no color shifting by performing the positioning between the electrode structure and the light emission means while employing the deflection electrode splitted into the plural pairs as the deflection means and applying the different deflection voltage on each pair. CONSTITUTION:The deflection means is splitted electrically into three pairs of deflection electrodes where one electrodes B1-B3 in each electrode pair, for example, are connected in series through the resistors R1-R3 then the variable voltage is applied across them. Under this state the deflecting pulse signal is applied on the signal applying points 51, 52 and the signal voltage to be applied on the B1-B3 electrodes from the variable power source 53 is added with the voltage divided by the resistors R1-R3 where the voltage to be applied on the deflection electrode pair constituted of A1B1-A3B3 will differ step by step thus to shift the deflection distance of the electron beam each other. The shifting of the pitch against the phosphor substance is corrected by said slight shifting thereby the positional shifting can be corrected accurately resulting in the clear picture image.

Filed: 1979-11-15
Abstract: PURPOSE: To prevent the malfunction, by automatical stop or inverting run immediately after the detection when the reel shaft stop turning through the end of a tape.  
     CONSTITUTION: In a tape end detector, when a tape is wound up to the end and the reel shafts 23, 29 are stopped, and the exerted force to a shaking control plate 19 is lost. Thus, the plate 19 is not moved from the middle position, after it is returned to the middle position with the latch pin 17 of the 2nd slide control member 7. Accordingly, when the 2nd slide control member 7 moves toward the arrow A, latch pin 17 is in contact with the block section of the shaking control plate 19 and kindars the displacement over it for the 2nd slide control member 7. As a result, only the 1st slide control plate 1 greatly moves toward the arrow A, then the switching member 14 is turned and the end of tape is detected.

Nitrogen gas is then introduced into the vacuum vessel and a mixed gas thereof and argon gas is used as a reaction gas. Metallic titanium which is an evaporation source is irradiated with electron beams to form a gold hardened film 2 of titanium nitride on the surface of the heat-resistant substrate 1. The obtained substrate 1 is subsequently taken out of the vacuum vessel and placed in a heat-resistant glass vessel 4. Air is replaced with the nitrogen gas 3 and glass is simultaneously fused and sealed.
